What happens if the Tulsient XS unit fails? Will my existing RAID levels disappear?
No. If you have a number of hard drives with RAID groups configured on them and the Tulsient XS fails, it is possible to attach the hard drives to a new Tulsient XS unit without loss of data. Upon power up the Tulsient XS will recognize that the attached hard drives have been configured as a RAID group(s) and will automatically adapt to this information, providing the data as before.
